Hesperozygis plant named &#39;HES060101&#39;

ABSTRACT

A new and distinct  Hesperozygis  plant named ‘HES060101’, characterized by its compact, upright to outwardly spreading, mounding to trailing plant habit; freely branching habit; dense and bushy appearance; early and freely flowering habit; flowers that are purple blue in color; long flowering period; and good garden performance.

BOTANICAL DESIGNATION

Hesperozygis hybrida

CULTIVAR DENOMINATION

‘HES060101’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hesperozygis plant, botanically known as Hesperozygis hybrida and hereinafter referred to by the name ‘HES060101’.

The new Hesperozygis plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new uniform and freely-branching Hesperozygis plants with fragrance and attractive flowers.

The new Hesperozygis plant originated from a cross-pollination made by the Inventor on Apr. 19, 2005 in Higashiomi, Shiga, Japan of an unnamed proprietary selection of Hesperozygis kleinii, not patented, as the female, or seed, parent with Hesperozygis hybrida ‘Sunminbu’, disclosed in U.S. Plant Pat. No. 11,677, as the male, or pollen, parent. The new Hesperozygis plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Higashiomi, Shiga, Japan on Sep. 20, 2006.

Asexual reproduction of the new Hesperozygis plant by vegetative terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since Sep. 25, 2007 has shown that the unique features of this new Hesperozygis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Hesperozygis have not been observed under all possible combinations of environmental conditions and various cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘HES060101’. These characteristics in combination distinguish ‘HES060101’ as a new and distinct Hesperozygis plant:

-   -   1. Compact, upright to outwardly spreading and mounding plant         habit.     -   2. Freely branching habit; dense and bushy appearance.     -   3. Early and freely flowering habit.     -   4. Flowers that are purple blue in color.     -   5. Long flowering period.     -   6. Good garden performance.

The new Hesperozygis plant can be compared to plants of the female parent selection. Plants of the new Hesperozygis differ primarily from plants of the female parent selection in flower color as plants of the female parent selection have purple-colored flowers. In addition, plants of the new Hesperozygis flower for a longer period of time than plants of the female parent selection.

The new Hesperozygis plant can be compared to plants of the male parent, ‘Sunminbu’. Plants of the new Hesperozygis differ primarily from plants of ‘Sunminbu’ in the following characteristics:

-   -   1. Plants of the new Hesperozygis are more vigorous than plants         of ‘Sunminbu’.     -   2. Plants of the new Hesperozygis have narrower leaves than         plants of ‘Sunminbu’.     -   3. Plants of the new Hesperozygis flower earlier and for a         longer period of time than plants of ‘Sunminbu’.     -   4. Plants of the new Hesperozygis and ‘Sunminbu’ differ in         flower color as plants of ‘Sunminbu’ have lavender blue-colored         flowers.

Plants of the new Hesperozygis can be compared to plants of Saturozygis ‘Usmint2’, disclosed in U.S. Plant Pat. No. 16,790. In side-by-side comparisons plants of the new Hesperozygis differed primarily from plants of ‘Usmint2’ in flower size and color as plants of ‘Usmint2’ had longer pink-colored flowers that did not change in color with development. In addition, plants of the new Hesperozygis flowered later than plants of ‘Usmint2’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Hesperozygis plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hesperozygis plant. The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘HES060101’ grown in a container. The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘HES060101’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the winter and early spring in 16.5-cm containers in a coldframe greenhouse in Bonsall, Calif. During the production of the plants, day temperatures ranged from 10° C. to 35° C. and night temperatures ranged from 7° C. to 21° C. Plants were 24 weeks old when the photographs and description were taken.
